Abstract: An artery mapper is attached over a target artery, and includes a sensor array that detects pressure changes corresponding to pulsatile flow through the artery. The signals from the sensor array are processed to identify signals having a frequency within a predetermined pulsatile range, and that define an elongate path across the sensor array. A display is provided directly over the sensor array. A digital controller circuit receives the signals from the detector array, and produces an image on the display directly over the detected signals, providing the practitioner with an image corresponding to the location of the artery, to facilitate cannulation of the artery.

Abstract: A pressure pulse wave measurement apparatus includes: a sensor unit in which an element column including a plurality of pressure detection elements that are arranged side by side in one direction is formed; a pressing unit configured to press the sensor unit against a body surface of a living body; and a rotation control member configured to rotate the sensor unit about each of two axes that are orthogonal to a pressing direction of the pressing unit. The rotation control member includes a first member and a second member that are relatively rotated about a rotation axis extending in the pressing direction, and the first member and the second member both include a motion conversion mechanism for converting a rotational motion realized by the first member and the second member being relatively rotated, into a rotational motion of the sensor unit about each of the two axes.

Abstract: A system for providing a standard electrocardiogram (ECG) signal for a human body using contactless ECG sensors for outputting to exiting medical equipment or for storage or viewing on a remote device. The system comprises a digital processing module (DPM) adapted to connect to an array of contactless ECG sensors provided in a fabric or the like. A selection mechanism is embedded into the DPM which allows the DPM to identify body parts using the ECG signals of the different ECG sensors and select for each body part the best sensor lead. The DPM may then produce the standard ECG signal using the selected ECG signals for the different body parts detected. The system is adapted to continuously re-examine the selection to ensure that the best leads are selected for a given body part following a movement of the body part, thereby, allowing for continuous and un-interrupted ECG monitoring of the patient.

Abstract: In one aspect, a photoplethysmograph system to measure a user's heart rate includes one or more light-emitting diodes (LED) that provide a constantly-on light signal during a measurement period. The one or more light-emitting diodes are in optical contact with an epidermal surface of the user. The one or more light-emitting diodes emit a light signal into the tissue of the user, and wherein the tissue contains a pulsating blood flow. A light-intensity sensor circuit converts the reflected LED light from the tissue into a second signal that is proportional to a reflected light intensity. The second signal includes a voltage or current signal. A computer-processing module calculates the user's beat-to-beat heart rate from the second current signal.
